However, after planning the party and as Anna is being led on a "party treasure hunt," by following a string that winds through the kingdom, Elsa finds that she has caught a cold. She starts sneezing and unknowingly produces a group of small snowmen much like Olaf with each sneeze, who proceed to wreak havoc with the birthday party's decorations, much to Kristoff's chagrin as they have been left by Elsa to watch the birthday decorations to make sure Anna's birthday is perfect. While Elsa takes Anna on the hunt, Kristoff, Sven, and Olaf try to control the little snowmen and fix back the decorations in time for Anna and Elsa's return to the castle.
